You have 96 feet of fencing to enclose a rectangular pen for your dog. the pen should be three times long as it is wide. write and solve and equation find the dimensions of the pen.

length = 36 ft; width = 12 ft

Step-by-step explanation:

Let the width be x.

The length is 3x.

The perimeter is the sum of two lengths and two widths, and it equals 96 ft.

3x + 3x + x + x = 96

8x = 96

x = 12

Width = x = 12 ft

Length = 3x = 3(12 ft) = 36 ft

 Required equation :

Dimensions of the pen:

Width = 12 feet and Length =36 feet.

Step-by-step explanation:

Let w be the width of rectangular pen, then the length of the rectangular pen will be 3w.

We know that the perimeter of rectangle is given by "2length+2width".

Perimeter of rectangular pen = 2(3w)+2(w) =6w+2w=8w       (1)

Given : You have 96 feet of fencing to enclose a rectangular pen for your dog.

i.e. Perimeter of rectangular pen  = 96 feet               (2)

From (1) and (2), we get

[Divide both sides by 8]

Thus, width = 12 feet and length = 3(12)=36 feet.

the answer to this question is 3/19

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
